11. Parallel Lines Review. Proof, Parallel and Perpendicular Lines. Theorem: If two lines in the same plane are perpendicular to the same line, then the lines are parallel to each other. B) If two parallel lines are cut by a transversal, then the alternate exterior angles are congruent. 8. Draw a transversal to the parallel lines. Play this game to review Geometry. Do your answers to Item 4 confirm the conjectures you made in Item 3? Prove:If a transversal is perpendicular to one of two parallel lines, it is perpendicular to the other line. If the two lines intersect at a point, the vertical angles formed are congruent. Parallel and. It also makes a right angle with the line segment.

Honors Geometry Chapter 3 Proofs Involving Parallel and Perpendicular Lines Practice Proofs Involving Geometry Unit 2 Parallel Lines and Proof. Two parallel lines are coplanar. In a plane, if a transversal is perpendicular to one of two parallel lines, then it is perpendicular to the other line. Same-side exterior angles: Angles 1 and 7 (and 2 and 8) are called same-side exterior angles — they’re on the same side of the transversal, and they’re outside the parallel lines. When lines are parallel, they will never intersect (touch/cross) because they have the same slope, and are therefore always the same distance apart (equidistant). The lines below are parallel. In today’s lesson, we will see a step by step proof of the Perpendicular Transversal Theorem: if a line is perpendicular to 1 of 2 parallel lines, it’s also perpendicular to the other. Parallel and Perpendicular Lines. a line that intersects two or more coplanar lines in different points. a statement or conjecture that has been proven and established as true without a doubt. Similarly, the other theorems about angles formed when parallel lines are cut by a transversal have true converses. To find a perpendicular slope: In other words the negative reciprocal When the lines meet to form four right angles, the lines are perpendicular. Start studying Unit 1: Proof, Parallel, and Perpendicular Lines. a ray that divides the angle into two congruent adjacent angles. Lesson 7-1 Parallel Lines and Angle Relationships 4.
